Abstract
A method and a device for regulating current from an inverter supplying three-phase excitation signals to an induction motor. Two of the three phase currents are converted to digital signals which are sent to a microprocessor. The microprocessor converts the digital signals into a waveform angle signal and a waveform modulation constant signal. The switching signals for the inverter are generated in response to the waveform angle signal and the waveform modulation constant signal.
